INVENTOR i AITORNEYS Patented Nov. 7, 1933 UNITED STATES PAPER RECEPTACLE James D. Reifsnyder, Flushing, N. Y., assignor to Lily-Tulip Cup Corporation, New York, N. Y., a corporation of Delaware Application June 2, 1932. Serial No. 614,863

3 Claims.

This invention relates to paper receptacles and more particularly to such receptacles adapted to serve as containers having closure means adapted to be readily removed and inserted 5 therein. It is to be understood that the term paper is intended to cover paper or the like fibrous sheet materials or other suitable sheet materials readily adapting themselves to the type of construction herein described.

The class of device to which the invention is particularly adapted finds a wide use as a means for packing and shipping edibles of various kinds and classes; and for this reason it is desirable that such receptacles have closure means which may be repeatedly removed and replaced as the contents are successively partially withdrawn, in order that the unused portion of the contents will be kept in proper condition for consumption.

In the merchandising, handling and shipping of such containers, it is customary to handle the same with the covers or closure means removed therefrom, and in the case of the majority of such receptacles it is customary to make them tapered so that they might be nested together, and under such conditions it is necessary that the receptacles and closure means be disassembled.- Consequently, in handling receptacles of this nature it has been found that the edge or lip of the receptacle is subject to considerable distortion or mutilation, which not only detracts from the value of the receptacle but makes it difficult to insert and withdraw the closure means.

Furthermore in the repeated insertions and withdrawals of the closure means it has been found that the lip of the receptacle becomes damaged or distorted, thus further detracting from the quality of the article.

An object of this invention is to produce an article possessing the advantages and free from the objections heretofore referred to; and at the same time providing an article which might be economically and commercially manufactured.

I This invention consists in the novelfeatures, arrangements and combination of parts embodied by way of example in the article hereinafter described as illustrating the preferred form of the invention, and the invention will be more particularly pointed out in the appended claims.

Further objects, features and advantages 0f/ the invention will appear from the following specification and claims taken in connection the accompanying drawing, in which Fig. 1 is a perspective view of a receptacle showing suitable closure means inserted therein, and

Fig. 2 is a segmental longitudinal sectional view showing in further particularity the structural features.

The receptacle proper is formed with a tubular side wall 1 of multi-ply thickness, to the lower end of which is suitably fastened the bottom 2. Adjacent the upper end of the tubular body 1 is formed an internal annular recess 3 as by 5 means of a rolled bead 4; such recess furnishing a seat for accommodating a suitable closure, such as the closure disc 5, which is preferably provided with a suitable handle 6 by means of which the same may be withdrawn and reinserted.

That portion of the tubular wall 1 which extends above the recess 3 provides a suitable lip wall 7, which is flared outwardly and upwardly to provide a tapering guideway for readily centering the cover 5 and guiding the same to its seated position within the recess 3. In order that this tapered guide may retain its useful function in this respect it is'extremely important that it be maintained in a substantially undisso torted condition, and furthermore it is desirable that the guiding lip gradually approach the-lip wall 7 in order that the upper edge of the lip be not distorted or deformed in use. In order to bring about these jointly desirable results, I have provided the upper edge of the lip with a substantially circular rolled edge 8. Such a rolled edge must be made by a curling operation effected by curling the upper edge of the container to form the lip, as distinguished from a folding operation which would be made by making oneor more folds in the paper to form the lip. I have found that the best results are obtained when the lip is so constructed that the distance between the lower edge of the roll 8 and the upper edge of the bead 4 be kept to a length substantially the same as the diameter in cross section of the rollededge'8. From the standpoint both of obtaining a desirable product and also of obtaining the optimum structural condition, the distance between the rolled edge of the lip' and the recess preferably should be equal to the cross sectional diameter of the rolled edge of the lip 8.

.It will be noted that the taper of the lip wall '7 is such that if the line of said tapered wall be extended downwardly, it will form a reentrant angle with the main wall of the tubular body 1; which angle is designated on Fig. 2 as 9. This angle is designated in this manner in order to emphasize the fact that in a tapered receptacle, such as the one disclosed on the drawing, the taper of the lip wall 7 preferably is greater than the normal taper of the body of the receptacle. In this manner I have produced a guiding lip having a gradually curved entering edge which merges with the downwardly and inwardly inclined lip wall? to a point adjacent the shoulder-of the recess 3; and the lip wall '7 is retained in its desired tapering condition jointly by means of the bead 4 and the rolled edge 8, which act as reinforcing bands strengthening the outer marginal edges of the lip wall 7. Furthermore, the entire receptacle is provided. with this doubly reinforced lip so positioned and constructed as to produce not only the optimum structural characteristics but also the optimum manufacturing conditions.

Having thus described my invention with particularity with reference to its preferred form, it will be obvious to those skilled in the art, after understanding my invention, that other changes and modifications may be made therein without departing from the spirit and scope of my invention, and I aim in the appended claims to cover such changes and modifications as are within the scope of the invention.

What I claim'is:

1. In a paper receptacle, the combination of, a multi-ply tubular side wall and a bottom permanently fastened therein, said side wall having an annular recess interior thereof for receiving a removable closure and spaced downwardly from the upper edge thereof to provide a lip, said lip being flared outwardly and upwardly to provide a tapered guide for the easy reception of said closure and having an annular rolled rim edge spaced upwardly from' said recess for a distance approximately equal to the cross sectional diameter of said rolled edge.

2. A paper receptacle of the character described comprising a multi-ply tubular body having a rolled edge lip presenting an inwardly curved surface which merges into an inwardly downwardly inclined lip wall, said lip wall being so tapered that a line extending downwardly therefrom makes a reentrant angle with the inside of the main wall of said body, and an inner peripheral recessfor receiving a removable closure, said recess being positioned in spaced relation relative to said edge" for a distance approximately equal to the cross sectional diameter of said edge, whereby said lip provides a tapered guide for centering said closure during insertion and the contour of said guide is reinforced and maintained'bysaid spacedapart edge and recess.

3. In a paper receptacle, the combination of,

a multi-ply tubular sidewall and a bottom;

fastened therein, said side wall-having an annular seat interior thereof for receiving a removable closure and spaced downwardly from the upper edge thereof to provide a lip, said lip having an annular rolled rim edge spaced upwardly from said seat for a distance approximately equal to the cross sectional diameter of said rolled rim edge.
